On January 9, 2009, TÜV SÜD Shanghai Branch issued NO.001 thin-film PV module certificate to GS-Solar, thereby making our company the first thin-film module manufacturer in China to receive IEC 61646 Certification. On February 19, 2009, TÜV Rheinland also issued an IEC 61646 certification to GS-Solar. Currently, GS-Solar is the only thin film solar module manufacturer in China to receive such product quality certification. Certifications from both TÜV SÜD and TÜV Rheinland confirm GS Solar's modules adhere to IEC’s stringent requirements for functional and mechanical capabilities for long-term operation under open-air environments. Our customers expect our modules to last for the duration of their long dated projects, so we are determined to ensure our products live up to the promises.
